I have an Airport Time Capsule and I am running one of my old Airport Extremes (Flying Saucer) as a direct-connected satellite for my gaming system. I was running X.7.5 on my laptop until yesterday. In order to manage the Airport Extreme, I had to run Airport Utility 5.6 in addition to he default Airport Utility (for Time Capsule). I upgraded to X.11.2 to solve some compatibility issues with other tools I needed and now Airport Utility 5.6 won't run. The new Airport Utility won't even stumble through like the old version would - it just will not play along.
What options are available to me to manage the Airport Extreme's settings in the future? Upgrading to a "newer/supported device *could* be an option but is not preferred - The Time Capsule's signal will not go as far as I need and I have *two* AirPort Exreme's which work great (one includes an dial-up modem BTW).
If all else fails and upgrade is the only solution, I am willing to barter/trade what I got (and love) for what will work if someone is jonesing for two (flying saucer) Extremes.
Please let me know how two make 'em work with what I got or who wants to take 'em off my hands.
